Radial load is applied in a direction inclined to a plane that passes through the axis of each axis perpendicular to the plane (meaning the direction on the opposite side of the other axis)2
A rolling bearing for a book shaft is a device in which two outer rings are self-centeringly supported in an inner bore of a casing common to both shafts, with the spherical outer circumferential surfaces of both outer rings facing each other. The above-mentioned area is formed as a flat part, the mutual distance between the axes of both shafts is smaller than the outer diameter of the outer ring, and the two outer ring pressures having a spherical inner peripheral surface are connected to each other. It relates to a type in which the inner dimension of the casing inner hole measured in the direction perpendicular to a common plane is greater than or equal to the axial length of the outer ring and the distance between both end faces of the outer ring.
このようなラジアル転がり軸受は装置は、たとえば合成

れるものである。Such a radial rolling bearing is used, for example, as a bearing for a screw shaft in a twin-screw extruder for synthetic resin.

的に駆動する平ギヤ伝動機構のかみ合い力が各軸に対し
て前記の方向に作用するからである。In this case, each shaft receives a radial load in a direction inclined outward at an angle of approximately 60° to 75° with respect to a common plane containing the axes of both shafts. This is because the meshing force of the spur gear transmission mechanism that is driven by the shaft acts on each shaft in the above-mentioned direction.
外輪の外周面が球面であって、ケーシングの球面の外輪
産肉で調心可能に支承されている転がり軸受けは公知で
ある。A rolling bearing is known in which the outer peripheral surface of the outer ring is a spherical surface and is supported so as to be able to align with the spherical outer ring wall of the casing.
更に、互いに平行々２本の軸を互いにできるだけ接近さ
せて軸受けするために、両方の外輪の外周面の互いに向
き合う側の区域を平面部として形成することも公知であ
る。Furthermore, it is known to design the regions of the outer circumferential surfaces of the two outer rings facing each other as flat sections in order to support two mutually parallel shafts as close as possible to each other.
いずれにせよ外輪が調心可能である軸受けをケーシング
内にそう人するために、従来は大抵はケーシングを２部
分に分割して構成していた。In any case, in order to accommodate a bearing whose outer ring can be aligned within the casing, the casing has traditionally been divided into two parts.
しかしながらこのような２部分より成るケーシングは製
作費が高価であるばかりでなく、組み立てられた場合に
両方のケーシング半部が全く均一に荷重支持作用を行う
という保証がない。However, such two-part casings are not only expensive to manufacture, but there is no guarantee that the two casing halves will carry out the load-bearing action quite evenly when assembled.
他面において１本の軸のための、外輪が調心可能である
軸受は装置に釦いて、ケーシングを一体のままにしてお
くために外輪塵の直径方向で互いに向き合った２つの区
域の所で一方の端面側に切り欠き部をそれぞれ形成して
おくことは公知である。On the other hand, the bearing for one shaft, the outer ring of which is alignable, is installed in the device in two areas diametrically opposite each other in the outer ring to keep the casing in one piece. It is known to form notches on one end surface.
このようにすると、外輪をその外輪塵に対して同軸的な
状態から９０°旋回させた状態でケーシング内にそう人
し、次いでケーシング内で外輪を再び９０°旋回させて
外輪塵に対して同軸的な位置にもどすことが可能である
。In this way, the outer ring is placed in the casing with the outer ring turned 90 degrees from the coaxial state with respect to the outer ring dust, and then the outer ring is turned 90 degrees again within the casing and coaxial with the outer ring dust. It is possible to return it to the correct position.
しかしながらこの場合外輪塵の２箇所に形成される切り
欠き部は外輪外周面と外輪庫内周面との接触面を著しく
減少させ、外輪塵の荷重支持能力の低下が問題とｉるこ
とかある。However, in this case, the notches formed at two locations on the outer ring dust significantly reduce the contact surface between the outer circumferential surface of the outer ring and the inner circumferential surface of the outer ring storage, and a reduction in the load-bearing capacity of the outer ring dust may become a problem. .
これに対し互いに平行な２本の軸のための転がり軸受は
装置においては、既に述べたように両方の外輪塵が互い
に部分的に交差し合っているようにすると、この交差箇
所を利用すれば一方の外輪のそう人のためには外輪塵に
切り欠き部を形成して釦かなくてもよい。On the other hand, in the case of a rolling bearing for two mutually parallel axes, as mentioned above, if both outer rings partially intersect with each other, then this crossing point can be used. For those who want to use one of the outer rings, it is not necessary to form a notch in the outer ring so that there is no button.
す女わちこの場合まず一方の外輪をその外輪塵に対して
同軸的な状態から９０°旋回させかつ前記交差箇所の方
にずらした状態でケーシング内にそう人し、次いで外輪
をケーシング内で前記交差箇所とは逆の方向にずらせて
外輪外周面を外輪庫内周面に当て付けてから、ケーシン
グ内で外輪を再び９０°旋回させて外輪塵に対して同軸
的な位置にもどすことができる。In this case, one outer ring is first turned 90 degrees from its coaxial position with respect to the outer ring, and placed in the casing with the outer ring shifted toward the intersection, and then the outer ring is placed inside the casing. After shifting the outer ring in the opposite direction to the intersection point and abutting the outer circumferential surface of the outer ring against the inner circumferential surface of the outer ring storage, the outer ring can be turned again by 90 degrees within the casing to return to a position coaxial with respect to the outer ring dust. can.
要するに一方の外輪をケーシング内に組み込むためには
外輪塵に切り欠き部を形成してかく必要が女い。In short, in order to incorporate one of the outer rings into the casing, it is necessary to form a notch in the outer ring.
しかしｉから第２の外輪を組み込むためには依然として
所属の外輪塵に切り欠き部を形成して釦かなければ々ら
ない。However, in order to assemble the second outer ring from i, it is still necessary to form a notch in the corresponding outer ring and press the button.
このような切り欠き部はたとえそれが１つしか形成され
ていｉくても、前記のラジアル荷重を受ける外輪塵区域
にまで達しているので、この区域にかける外輪外周面と
外輪庫内周面との接触面を減少させることに変わりｉい
。Even if only one such notch is formed, it reaches the outer ring dirt area that receives the radial load, so the outer circumferential surface of the outer ring and the inner circumferential surface of the outer ring housing are This is an alternative to reducing the contact surface with the
そこで本発明の目的は、このようなラジアル荷重を受け
る外輪塵区域にかける外輪外周面と外輪庫内周面との接
触面の減少を長小眼にとどめることである。Therefore, an object of the present invention is to minimize the reduction in the contact surface between the outer circumferential surface of the outer ring and the inner circumferential surface of the outer ring housing, which is applied to the outer ring dust area that receives such radial load.
この目的を達成するために本発明の構成では、最初に述

記共通の平面に沿った断面で見た形状にほぼ合致してい
るようにした。In order to achieve this object, the present invention provides a radial rolling bearing of the type mentioned at the outset, in which the casing is constructed in one piece, and one outer ring is opposite to the flat part of its outer circumferential surface. has two flat or slightly curved surfaces sloped in a roof-like manner opposite each other from both end faces when viewed in cross section along said common plane, and Outer ring dust for the one outer ring is
In the area overlapping the roof-like sloping surface,
A notch is provided on one end surface, and the shape of the notch when viewed in the axial direction of the casing corresponds to the area of the outer circumferential surface of the outer ring where the roof-like sloped surface is provided. It was made to approximately match the shape seen in the cross section along the common plane.

最小限にとどめられるのである。In other words, the shape of the notch viewed in the casing axis direction is
It has straight or slightly curved line segments corresponding to the flat or slightly curved surfaces that are inclined to each other in a roof-like manner, and does not follow the shape of an arc as a whole; As a result, the reduction in the contact surface between the outer circumferential surface of the outer ring and the inner circumferential surface of the outer ring housing can be kept to a minimum.

触面は本発明のような切り欠き部を形成すればこの区域
全体の接触面のほぼ）〜＋にすぎｉいが、従来のよう々
円弧形の切り欠き部を形成する場合にはほぼ命にも達す
るのである。Specifically, when viewed in the axial direction of the casing, the contact surface cut out in the outer ring dust area that receives radial load will be reduced by forming the notch part as in the present invention. However, in the case of forming an arc-shaped notch as in the conventional case, it can reach almost the limit.

根状に傾斜している２つの面の間に球面の外周面区分が
残されて釦シ、これにより外輪塵の荷重支持作用が屋根
状に傾斜している面が設けられている区域で中断される
ことが避けられる。In one embodiment of the invention, a spherical outer peripheral surface section is left between the two surfaces facing each other and sloped in a roof-like manner, whereby the load-bearing action of the outer ring dust is roof-like. Interruptions in areas provided with inclined surfaces are avoided.
このためには、互いに向かい合って屋根状に傾斜してい
る２つの面の成す角度をほぼ９０°〜１００’にすると
よい。For this purpose, the angle formed by the two roof-like sloped surfaces facing each other should be approximately 90° to 100'.
以下に訃いては図面に示した実施例に基づいて本発明の
詳細な説明する。The present invention will be explained in detail below based on the embodiments shown in the drawings.
図示のラジアル転がり軸受は装置は一体のケーシング１
を有して釦り、このケーシング１の内孔に２つの外輪２
及び３が支承されている。The illustrated radial rolling bearing has an integrated casing 1.
There are two outer rings 2 in the inner hole of this casing 1.
and 3 are supported.
各外輪２．３と所属の内輪５との間で円柱状の転動体４
（ころ）が転動する。A cylindrical rolling element 4 is formed between each outer ring 2.3 and the associated inner ring 5.
(Rollers) roll.
この場合内輪５はつば６によって転動体４を軸平行に案
内している。In this case, the inner ring 5 guides the rolling elements 4 parallel to the axis by means of the collar 6.

れぞれ安全リング７がはめ込まれて卦り、これらの安全
リングは転がり軸受は装置によって２本の軸を軸受けす

とを防止する。Safety rings 7 are fitted into the inner circumferential surface of the outer ring 2.3 near both end surfaces 13, and these safety rings are used for rolling bearings. 5 and the rolling elements 4 are prevented from falling off from the outer ring 2.3.
外輪２及び３は球面の外周面８を有してかり、これに相
応してケーシング内孔に形成されている外輪塵１２も球
面の内周面を有している。The outer rings 2 and 3 have a spherical outer peripheral surface 8, and correspondingly the outer ring dust 12 formed in the casing inner hole also has a spherical inner peripheral surface.
したがって外輪２，３はケーシング内孔に調心可能に支
承されていることに彦る。Therefore, the outer rings 2 and 3 are supported in the inner bore of the casing so as to be able to align with each other.
両方の外輪２，３の球面の外周面８は互いに向き合う側
の区域を平面部９として形成されていて、第１図及び第
２図から分かるようにこれらの平面部９の間にはすきま
が残されてかり、したがって両方の外輪２，３の調心運
動は支障なく行われる。The spherical outer circumferential surfaces 8 of both outer rings 2 and 3 are formed with planar portions 9 in the regions facing each other, and as can be seen from FIGS. 1 and 2, there is no gap between these planar portions 9. The centering movement of the two outer rings 2, 3 therefore takes place without any problems.
このように両方の外輪２，３が平面部９を有しているこ
とにより、両方の外輪塵１２は互いに部分的に交差し合
うことになり、２本の軸を互いに接近させて軸受けする
ことができる。Since both the outer rings 2 and 3 have the flat parts 9 in this way, the two outer rings 12 partially intersect with each other, and the two shafts can be brought close to each other for bearing. Can be done.
すなわち両方の軸の軸線の相互間隔は各外輪２，３の外
径よりも小さい。That is, the distance between the axes of both shafts is smaller than the outer diameter of each outer ring 2,3.

The shape of the cutout 11 viewed in the casing axial direction (as seen in FIG. 1) approximately corresponds to the shape seen in FIG. We are doing so.
女か第１図において符号αは各軸が受けるラジアル荷重
の方向を示す。In FIG. 1, the symbol α indicates the direction of the radial load that each axis receives.
この方向は両方の軸の軸線を含む共通の平面（ｎ−ｎ平
面）に対してほぼ６０°〜７５°斜め外方に傾斜した方
向である。This direction is a direction inclined outwardly by approximately 60° to 75° with respect to a common plane (nn plane) containing the axes of both axes.
特に、一方の外輪３のための外輪塵１２はこのラジアル
荷重が作用する箇所から前記共通の平面（ＩＩ−ｎ平面

いなければならない。In particular, the outer ring dust 12 for one outer ring 3 must have sufficient load-bearing capacity over the area from where this radial load acts toward the common plane (II-n plane).
図示のラジアル転がり軸受は装置の組み立ては次のよう
にして行われる。The illustrated radial rolling bearing is assembled as follows.
まず、第１図で見て右側の外輪２をその外輪塵１２に対

シング１内にそう人する。First, the outer ring 2 on the right side as seen in Fig. 1 is turned from the state where it is coaxial with the outer ring dust 12 (the state shown in Fig. 1) to the A person is placed in the casing 1 with the axes thereof perpendicular to each other and shifted toward the left side as viewed in FIG.
このことが可能であるのは、既に述べたようにケーシン
グ内孔の内法寸法Ｌ８ と外輪の軸方向長さＬ２との間
にＬ□≧Ｌ２の関係があるからである。This is possible because, as already mentioned, there is a relationship L□≧L2 between the inner dimension L8 of the casing inner hole and the axial length L2 of the outer ring.
次いで外輪２をケーシング１内で第１図で見て右側に向
かってずらせて外輪２の外周面８を外輪塵１２の内周面

However, without shifting towards the right side as seen in Figure 1,
There are so many people inside the casing 1.
このことが可能であるのは切ジ欠き部１１が外輪塵１２
に形成されているからである。This is possible because the notch 11 has outer ring dust 12.
This is because it is formed in
なおこの場合既に外輪２がケーシング１内に支承されて
いるので、外輪３を第１図で見て右に向かってずらせて
そう人することは不可能である。In this case, since the outer ring 2 is already supported in the casing 1, it is impossible to shift the outer ring 3 toward the right as viewed in FIG.
次いでケーシング１内で外輪３を再び９０°旋回させて
第１図及び第２図に示した状態にもどすと、組み立てが
完了する。Next, the outer ring 3 is turned 90 degrees again within the casing 1 to return to the state shown in FIGS. 1 and 2, and the assembly is completed.
